Description

Technical Field

[0001] The present application relates to the technical field of fish fry feeding equipment, and in particular to a quantitative powder feeder for fish fry farming. Background Art

[0002] In the process of aquaculture, powdered feed is usually used to feed fish fry, and because fish fry have weak risk resistance, farmers usually use nursery boxes to raise the fish fry individually. After the fish fry grow up, they are transferred to ponds for breeding to ensure the survival rate of the fish fry.

[0003] Since the number of fry cultured in a single nursery box is limited, in order to ensure the normal growth of fry, multiple nursery boxes are usually set up in the farm. In addition, the upper limit of fry that can be accommodated in a single nursery box varies according to the species of fry cultured. In addition, the food intake of different fry is also different, so when feeding, the feeding amount of each nursery box needs to be calculated separately to avoid overfeeding or underfeeding. The commonly used feeding method is to weigh the required feeding amount for each nursery box in advance, and then add the feed to the corresponding nursery box in turn. This method requires weighing every time feeding, which is very troublesome and has low feeding efficiency. It is not suitable for large-scale fry farming. Utility Model Content

[0027] See also Figure 1 , 2 A quantitative powder feeder for fry farming, comprising a bottom plate 1, a hopper 2, a feeding mechanism 4, a feeding trough 6, a feeding wheel 8, and a motor 7. A housing 3 is fixedly mounted on the bottom plate 1, and the housing 3 protects the various components of the device, while also preventing the device from being mechanically damaged by accidental touch by staff during operation. A hopper 2 is fixedly mounted on the top of the housing 3, a feeding mechanism 4 for preventing blockage is mounted at the bottom of the hopper 2, and a feeding wheel 8 is rotatably mounted at the discharge port of the hopper 2, three quantitative grooves 81 are evenly opened on the wheel surface of the feeding wheel 8, and a feeding trough 6 is mounted below the feeding wheel 8, and a motor 7 for driving the feeding wheel 8 is also mounted on the bottom plate 1. When in use, the powder is added into the hopper 2, and the feeding wheel 8 is driven to rotate by the motor 7. When the quantitative groove 81 is opposite to the discharge port of the hopper 2, the powder falls into the quantitative groove 81 under the action of gravity. As the feeding wheel 8 rotates, the powder in the quantitative groove 81 falls into the feeding groove 6, and slides into the seedling box 13 through the feeding groove 6. The total feeding amount can be controlled by controlling the number of rotations of the motor 7 through the controller.

[0028] In some embodiments, see Figure 3 Two first support rods 83 are vertically symmetrically arranged on the bottom plate 1, and a rotating shaft 82 is rotatably installed between the two first support rods 83. A feeding wheel 8 corresponding to the discharge port of the hopper 2 is fixedly connected to the rotating shaft 82. Since the hopper 2 and the feeding wheel 8 are in sliding connection, in order to reduce powder leakage, the connection between the hopper 2 and the feeding wheel 8 is sealed; a transmission wheel 84 is also fixedly connected to the rotating shaft 82, and a pulley is fixedly connected to the output shaft of the motor 7, and the pulley and the transmission wheel 84 are connected by a belt.

[0029] In some embodiments, see Figure 5The feeding mechanism 4 includes a turntable 41, a slide bar 44, a first spring 45, and a feeding plate 46. The turntable 41 is fixedly connected to the rotating shaft 82. The slide bar 44 is slidably connected to the side wall at the discharge port of the hopper 2, and a contact block 43 is provided at one end of the slide bar 44 close to the turntable 41, and the contact block 43 is located on the outside of the hopper 2. A feeding plate 46 is provided at the other end, and the feeding plate 46 is located on the inside of the hopper 2. A first spring 45 is provided between the contact block 43 and the hopper 2. The first spring 45 is always in a compressed state. The contact block 43 can always be pressed against the side of the turntable 41 by the first spring 45. A protrusion 42 corresponding to the contact block 43 is also provided on the side of the turntable 41. During use, during the rotation of the turntable 41, the protrusion 42 will continuously lift the contact block 43. When the protrusion lifts the contact block 43, the first spring 45 is compressed, and the slide rod 44 extends into the hopper 2, driving the feeding plate 46 to move, stirring the powder at the discharge port of the hopper 2 to prevent the powder from being squeezed at the bottom of the hopper 2 and causing the discharge port to be blocked, thereby ensuring that the powder can smoothly fall into the quantitative slot 81, thereby ensuring the stability of the feeding process. After the contact block 43 passes the protrusion, the feeding plate 46 is reset under the action of the first spring 45.

[0030] In some embodiments, see Figure 3 , 4 In order to prevent the powder in the quantitative groove 81 from spilling everywhere, a drop pipe 5 is sleeved on the outside of the feeding wheel 8. The drop pipe 5 is only open at the bottom, and the opening position is directly opposite to the feeding groove 6. When the powder in the quantitative groove 81 is spilled under the action of gravity, the powder can be introduced into the feeding groove 6 through the drop pipe 5. Furthermore, since the powder has a certain degree of adhesion, it is easy to cause part of the powder to always adhere to the quantitative groove 81, thereby affecting the accuracy of feeding. A scraper component 9 corresponding to the feeding wheel 8 is also installed in the drop pipe 5;

[0031] The scraper assembly 9 includes a scraper 91, a telescopic guide rod 92, and a third spring 93. One end of the telescopic guide rod 92 is fixedly connected to the inner side wall of the drop tube 5, and the other end is installed with a scraper 91 corresponding to the quantitative groove 81, and a third spring 93 is arranged between the scraper 91 and the drop tube 5. The third spring 93 is always in a compressed state, so that the scraper 91 always presses against the feeding wheel 8. When the feeding wheel 8 rotates, under the action of the third spring 93, the scraper 91 always presses against the wheel surface of the feeding wheel 8. When the scraper 91 passes through the quantitative groove 81, the powder adhered to the quantitative groove 81 can be scraped off to ensure the consistency of the charging amount of the quantitative groove 81, thereby ensuring the accuracy of the total amount of feeding. Further, in order to facilitate the transition of the scraper 91 between the wheel surface of the feeding wheel 8 and the quantitative groove 81, the edge of the quantitative groove 81 is chamfered.

[0032] In some embodiments, see Figure 3The feeding trough 6 is connected to the second support rod 61 through the second spring 62. The second support rod 61 is provided with four pieces, two long and two short. The shorter second support rod 61 is fixedly connected to the front side of the bottom plate 1, and the longer second support rod 61 is fixedly connected to the rear side of the bottom plate 1, so that the feeding trough 6 is tiltedly installed on the bottom plate 1 through the second support rod 61. Furthermore, a vibrator 63 is also installed at the bottom of the feeding trough 6. When the powder falls into the feeding trough 6, the vibrator 63 drives the feeding trough 6 to vibrate, so that the powder slides into the seedling box 13 to complete the feeding.

[0033] On the basis of the above embodiment, wheels 11 are installed at the bottom of the base plate 1, and a push handle 12 is provided at the rear of the base plate 1, so as to facilitate the staff to push the device to move between the seedling boxes 13. A storage box 10 is also provided on the base plate 1 for storing powder for convenient use.

[0034] Since the dosing groove 81 and the hopper 2 are misaligned in the initial state, an error may occur in the feeding amount of the first turn of the feeding wheel 8. This error is usually negligible compared to the overall feeding amount.

[0035] Specific working process:

[0036] Push the device to the seedling box 13 with feeding, align the feeding slot 6 with the seedling box 13, add powder into the hopper 2, start the motor 7, drive the feeding wheel 8 to rotate, the powder is continuously transported to the drop pipe 5 through the quantitative slot 81, and the quantitative slot 81 is continuously cleaned by the scraper 91 to avoid sticking of the material. By controlling the number of rotations of the motor 7, the total feeding amount is controlled, and there is no need to weigh the powder;

[0037] After the powder material falls into the feeding trough 6 from the bottom of the feeding pipe 5, the vibrator 63 is started to make the powder material slide along the feeding trough 6 into the seedling box 13, and the feeding is completed.
